CONVEYER CHAIN LINK l Filed April 9, 1948 \/\T Z fum-m5 INVENTOR.
HT To'RN EY This invention relates Patented Dec. 18, 71951 vir zanius, Fori Wayne Dairy Wayne, Ind., a; corpora Wayne, Ind., assignor to Fort Equipment Company, Fort tion of Indiana ApplieationApri-l 9, 1948, Serial No. 20,018
to a conveyor chain. More specifically, it relates to a link for a conveyor chain which is kmade by a vseries of punching and forming operations which may be carried out on a punch or other type of press.
It is an object of the rinvention to provide a conveyor chain link which is easy to manufacture.
Another object of the invention is to provide a link of the kind described which may be forined from nat, strip stock.
. Yet another object of the invention is to provide a link which is simple but sturdy.
A further object of the invention is to provide a link which utilizes strip stock economically and efficiently. n
Another object of a link which can be formed by of operations.
These and other objects will become apparent from a study of this specication and the drawing which is vattached hereto and is made a part hereof and in which: e Y
Figure 1 is a plan view of the strip and the blank which is punched therefrom.
Figure 2"is'a"planl` vie-w of the part after the first forming operation.
Figure 3 is an elevation of they part of: Figure 2.
Figure 4 -is a plan view of the link after the second forming operation showing the first-step informing the hinge. Y
Figure 5 is an elevation of the structure of Figure 4. y Figure 6 is a plan view of two of the finished links and their connecting means.
Figure 7 is an elevation of the Figure 6.
Referring now to Figure 1, the numeral I indicates the strip of metal such as stainless steel. or any other strip stock from which the link is to be formed.
The first operation is to punch out the blank 3 as shown in Figure l. This blank has a platform 5 which extends transversely of the axis A-A of the strip, two laterally extending arms V6 which are punched at 1 to receive a hinge pin 9 and which diverge from the platform, the saddle portion I4 which connects the arms and also connects them and the platform with the axially extending hinge tab Il. A notch is formed in the edge of the platform opposite the saddle and is slightly wider than the tab Il which is cut from it.
As noted above, the arms 6 diverge fromthe platform so that their free, outer ends are 'farther from the platform than their inner endsso the invention is to provide a small number structure of platform.
.the piece ninety 11 claims. (o1. 19a- 189) that` when the link is formed.,- the plane contains the centers of the holes 1 and the axis of the hinge will be parallel to the plane ofthe The blank thus formed is then insertedin a forming die which bends portions I3 of the arms 6 downwardly and outwardly from the saddle [4 substantially along the lines B-B which are parallel to the axis and then bends the lower ends i5 of the arms about the line C-C until they lie paralleli.- The distance between the inner faces of the ends l5 is made great enough to reecivethe hinge l1 which is formed from tab y I l.
The second forming operation, shown in Figures 4 and 5, is also performed in a diepand. bends degrees on a .suitable radius about the lines D-D, Ef-E and Fk F. The platform now occupies, the proper relation withzrespeot to the arms and .the hinge is partially formed so it need only be closed. o
rihe third and last forming operation completes the hinge l1 by bendingit substantially aboutv the axis G-Gr to close it. The final forinof. the link is shown in Figures 6 and 7. y
A hinge pin 9 is inserted through the holes 1 and the hinge of the adjacent link retaining. y washers I9 are crimped into :grooves 2l formed in the pin 9 adjacent the outer faces of the ends L5 of the arms. v
The teeth 23 of the driving sprocket 25 engage the hinge portions of the links as shown in Figure 'l to move the chain.v y f The notch 8 provides clearance for .the saddle It of the adjacent link if the chain sags through;- out any portion of its length.= Y. Y
The operation of the chain made of links formed as described is obvious and needs no description.
While I have disclosed a preferred form of my invention for purposes of illustration, it is obvious that various changes may be made in the construction and arrangement of parts thereof Without departing from the spirit of the invention. I do not, therefore, desire to be limited to the exact form disclosed but desire protection falling fairly within the scope of the appended claims.
What I consider to be new and desire to protect by Letters Patent of the United States of America is: p
